A COREORATION O.F NEW YORK METAL CONTAINER Applicaton filed April 2,1931. Serial No. 527,304.

The invention relates to new and useful improvements in a metalcontainer, and more particularly to a metal container where1n the coveror end is seoured thereto by a seal1ng strip or band which is forciblyremoved from the container for releasing the cover therefrom.

An object of the invention is to provde a container of the above typewhere1n a seal1ng gasket is forcibly pressed into sealing engagementwith the body of the conta1ner and cover, and is so disposed that uponremovmg the sealing strip the gasket is uncovered so that it can bereadily removed, thus breaking any vacuum in the container andfac1l1tating the removal of the cover ther efrom.

A further object of the invention is to provide a container of the abovetype wherein the upper face of the projecting portion of the coveroverlying the flange on the contamer body, and also the upper portion ofthe retaining strip, are substantially flat, and wherein said strip isheld on the contamer by a bead formed in the cover which 1s locatedbeyond the flange and which pro ects below the under face of the flange.

In the drawing F gure 1 is a side view of a conta1ner partly in sectionand embodymg the 1mprovements.

F igure 2 is an enlarged sect1onal v1ew of a portion of the containershow1ng the cover, the retaining strip and the seal1ng gasket in placeprior to the seal1 ng of the container.

Figure 3 is a similar v1e w but show1ng the lower portion of theretain1ng strip as pressed into sealing position f or seal1ng t heconta1ner and locking the strip to the conta1ner.

Figure 4: is a view similarto F1gure 2 but showing the retaining str1pand seal1ng gasket removed.

The invention is d1rected to a metal container wherein the body portion1s provided with a flange at the upper open end thereo f. Seated in theopen end for closing the same 1s a cover which has a central depressedportion fitting the opening in the container. The cover is also providedw1th a portlon which projects beyond and overlies the flange on the bodyof the container. The outer portion of the cover is crled downwardly,thence inwardly and upvvardly to form a bead which lies beyond the edgeof the flange of the container body. This bead is of reater thicknessthan the flange on the bo y, and therefore the lower edge of the bead isbeneath the lower face of the flange. A sealing gasket is placed in therecess between the bead and the wall of the body and beneath the flange.A scaling strip which is, when attached to the container, substantiallyU-shaped in cross section, overlies the cover and extends beneath thebead and the flange andis pressed against the sealing material forforcing the sealing material into tight sealing engagement with theflange and the bead. The bead also serves the function of holding theretaining strip on the container until it is forcibly removed therefrom.

Referring more in detail to the drawing, a container is shown whichincludes a body portion 1 having an end 2 secured thereto by a doubleseam 3. The body wall 1 at the upper edge.thereof is rolled or bentoutwardly to form a flange 4= which overhangs the outer vvall ofthecontainer body, that is the flange projects outwardly and issubstantiall horizontal at the extreme outer portion t ereof. Thecontainer is closed by a cover or end 5 which is formed with a depressedportion 6 fitting Within the open end of the container. The cover has aportion 7 which overlies the flange and projects beyond the end of theSame. The extreme outer portion of the cover is curled downwardly,inwardly and upwardly to form a bead 8. This bead is disposed beyond theedge of the flange 4:. The top face of the cover portion overlying theflange is substantially flat, and the bead is of such thickness that theextreme lower portion thereof is well below the lower face of the flange4 of the container body. This forms a recess in which a gasket 9 isplaced. The gas ket 9 is for the purpose of sealing the opening betweenthe end of the flange and the bead, and thus sealng the cover to thecontainer body.

The cover is scured to the container body by a retaining strip 10. Theretaining strip is substa.ntially U-shaped in cross section whenattached to thecontainer.

It includes flange and bead and for holdin said strip an upper portion11 which is substantially in place on the container until orcibly removed therefrom.

In testim0ny whereof, I aflix my signa flat, and which snugl fits theupper face of the cover portion7. t is curved to form to a shaping ofthe bead at its extreme outer portion, and is provided with asubstantially horizontally eXtending portion 12 which underlies theflange 4 an the bead 8. After the strip has been placed on the containerthe portion thereof is deflected 01 pressed upwardly, thus forcing thegasket into tight sealing contact with the flange and the bead.

This/upwardly deflected ortion serves the function also of holding t eretaining strig on the container until it is forcibly remove therefrom.It will be noted that in Figure 2 of the drawing that the distancebetween the portions 11 and 12 of the retaining strip, when applied tothe container, is slightly less than the distance from the upper face ofthe cover portion 7 to the extreme lower edge of the bead 8.Thereforethebead 8 serves as a retaining means to hold' the strip inlace on the container. In Figure 2 of the rawing the parts are shownwith the container strip in place but before it has been reformed toseal the container. In Figure 3 itis shown as tightly gripping thegasket and locked in place by the deflecting or deforming of the lowerpart of the retaming strip, In Figure 4 the retining strip and gasket isshown as removed, which can be done by grasping the end 10a of theretaining str1p and forcibly pulhng the same from the container. Thiscan be done by hand so that the retaining strip can be readily rcmoved.When the retaining strip is removed the gasket can be readiiy removed asit is. uncovered by the removal of the retaining strip, When the gasketis removed any vacuum which is resent in the container will be broken enthe cover can be readily lifted from the container. It can be readilyreplaced also for the purpose of reclosure purposes.

Having thus described the invention, what Iclaim as new and desire tosecure by Letters Patent, is

A .metal container comprising a body portion having a projecting flangeat its upper end, a cover having a depressed cntral portion fittingwithin the container body and a portion projecting beyond the flange ofthe container body, the outer edge of which is curled downwardly and.inwa1dly to form a bead disposed beyond the edge of the flange on thebody and of greater thickness than the flange, a sealing gasket benaththe flange on the can body for sealing the space between the edge of theflange and the bead on the cover and a retainin stri overl ing the coverand extending eneat the ange on the can body a portion of the retainingstrip beneath the lange and inside of the bead being deflected upwardlyfor pressing the seaI- ing material mto sealing contact with the tu re.
